The Fermi scale as a focus point of high-scale gauge mediation

Understand

We consider the minimal supersymmetric Standard Model with large scalar and gaugino mass terms at the GUT scale, which are generated predominantly by gauge-mediated supersymmetry breaking.

• For certain ratios of GUT-scale masses, determined by the messenger indices, large radiative corrections lead to a small electroweak scale in a way which resembles the well-known focus point mechanism.
• The Fermi scale, the gravitino mass and the higgsino masses are of comparable size.
• For a Higgs mass of about 124 GeV all other superparticles have masses outside the reach of the LHC.
